The lower I This invention relates to a material-handling apparatus for processing machines, and more particularly to such an apparatus for depositing in a predetermined position The principal object of the invention is the provision of an apparatus for positively cadva'ncingand arranging elements delivered from a processing machine.

the invention, parts whichhave been formed by being subjected to two continuously rotated forming rolls are positively'advanced to-a position where such-advancing means cooperates with an endless chain.y The end-' less chain being provided with elements for receiving the formed parts and beingdriven in timed relation with respect to the forming rolls carries the parts from the lower form-. ing roll to a position Where they are succes-' sively stacked inlcertain arrangement and position.

Referring now'to the drawings in which like numerals designate similar parts throughout the several views, it will be read ily observed that an upper forming roll 10 anda lower'forming roll 11 are mounted on and keyed to shafts 12 and 13, respectively, which are suitably journaledin a pair of In accordance with. the general features of paratus with the front supporting frame re forming roll is composed of a plurality of annular sections 15,116 and 17'and disposed .between these individual roll sections area pair of serrated disks 18-18, the purpose of which will be explained hereinafter. a

The forming rolls 10 and 11 are driven at the same peripheral speedin the direction roll'11 thereof. is positivelydriven by a source of power (not shown) applied to the shaft 13.

The upper forming roll 10 is driven from the shaft 13 by suitable gearing comprising a gear 22 secured thereto meshing with intermeshing pinions 23 -2 1;,v the latter of which meshes with a gear 25 secured tothe shaft 12.

In order to assure proper meshing of the gears and pinions thelatter are mounted? on a plate 26 which is made adjust-able as to po-- sition by means of a slot 27. l

Immediately abo'vetheforming roll 11v blank in the magazine is supported by/an arcuate plate 33 having an integral vertical portion'34 secured'to the lower end of the magazineSO. Positioned above the plate 33 and similarly secured is" a'companionplate shown by the arrows in Fig. 1. i The lowerj V with sufficient'space therebetween to permit the passage of one of the blanks '31. These plates are provided with slotsthroughwhich the projections 32 of therotary disks 18 pass and'th'e plates also cooperate to form a'guide for th'e'bla nkjs as the projections remove the blanks from the magazineand feed them be tween the forming r0lls.- '1

The foregoing structure has only been briefly described to give a workable understanding of the forming mechanism and a,

more detail and thorough understanding thereof can be obtained from the pending application of C. E. Nelson et al., Serial No. 197.651, filed June 9, 1927. 1 I

Mounted adjacent the underside of the forming r011 11 are two rollers 40-41'whichare rotatable upon shafts 4243, respectively, suitably journaled in the side frames 14-14. A pair of endless sprocket-chains 4444 are spaced and movable upon the roll ers 41 in such a manner that they follow the periphery of the forming roll for a short distance and engage the projections 32 of the disks 18 as will be explained. Each chain comprises a series of pairs of links 45-45 having an interconnecting link 46interposed between each pair of links and pivoted to freely move on apin 47; the other end of the link 46 is pivoted to another pair of links 4545 by an extended pin 48 which,

projects laterally from the chain so as to be engaged by the projections 32 of the disks 1'81'8' as clearly shown in Fig. 2. It will be readily understood from the foregoing that the rotating projections 32 of the disks 1818 incorporated in the lower forming roll serve to drive the chains 44-44 and their supporting rollers 4041, which form an endless conveyor for the parts formed from blanks 31.

To maintain the formed parts in contact with the lower roll as they issue from be tween the forming rolls, an arcuate leaf spring 52 is securely fastened at 53 on the egress side of the rolls. This spring extends around the lower forming roll 11 to a point where the conveyor chains come in contact with the roll when the formed parts are permitted to drop onto the links 45-45 of.tl1'ese chains. In case any formed part adheres to the roll a stripper spring 49 bearing'against the roll 11 at the point where the conveyor chains cease to follow the periphery of the roll is provided for forcing the formed part therefrom onto the chain. The interconnecting links 46 of the chains have an inclined upper. surface, such that the distance from the highest point 54 thereof down to the upper faces of the links 4545 is slightly greater than the thickness of the material being formed. A magazine 55 for receiving the formed parts is positioned at an incline directly in front of the roller 41. The bottom of this magazine is brought very close to the sprocket 41 and is provided with spaced slots 50 which permits the chains 44- 44 to pass therethrough and consequent- 1y deposit the formed part in the magazine. Inthe particular embodiment shown and described herein the formed parts are placed flatwise on the conveyor chains and are deliveredto or stacked edgewise in the magazine. The inclined top surfaces 54 of the links 46 in the chains transmit a camming action to the lastpart deposited in the magazine to force it forward or advance it therein to inake room for the next part as the parts are stacked in successive order.

. Theoperation of the apparatus is as follows: Power is applied to the shaft '13 and the forming rolls l0 ;ll are rotated in opposite directions. While the lower roll 11 re tates the projections 32 on the pair of disks 18 remove blanks 31 from the bottom of the magazine as they pass through the slots in the magazine guide plates 33-35. These projections 32 position and carry the blanks 31 through the forming rolls from whence they issue as formed parts. To prevent the formed parts from falling from the lower roll before they are properly positioned over the conveyor chains 44-44, the arcuate spring 52 is provided. As the formed parts travel past the end of this spring, they fall face downward upon the chains 4444 and are conveyed thereon to the magazine through the driving medium of the projecting pins 48 on the chains engaging the moving .projections 32 included in the forming roll 11. The chains pass through the slots 50-50 in the bottom of the magazine 55 and the parts are deposited edgewise, being advanced therein due to the inclined upper surfaces'54 of the interconnecting links 46. From the foregoing it will be clear that the formed parts are received in a given position and rapidly stacked in a predetermined. position through a simple and sturdy apparatus.

A modified form of the invention illustrated in Figs. 5 and 6 consists of replacing the chains with a pair of spaced disks '60 having serrations 61 analogous in shape to the upper surfaces of the chains 44-44 ex plained in connection with the first embodiment of the invention. These serrations 61 receive the parts, stack them 'edge'wise, and advance them in the magazine 55 in a manner similar to that already described for the chains of the previous embodiment. An arcuate spring 62 secured at 63 on the egress side of the forming rolls 1 0'11 maintains the parts in contact with the periphery of the lower forming roll 11 until the parts are in a position to be received by the disks 6060. The stripper spring 49 is provided for assuring that none of the parts will adhere to the surface of the forming roll 11. As the projections 32 carry the parts through the forming rolls 1011 past the arcuate spring 62, the serrations 61 take the formed parts face down and convey them to the mag azine 55. The disks .6O'60 are driven by means of the rotating projections of the roll 11 engaging theformed parts as they are supported between the serrations of the disks. These serrations pass through slots in the bottom of themagazine' 'and the foim'ed parts are deposited thereon and advanced therein due to the serrations push ing'the last part back to subsequently stack another part.

It is believed that the foregoingconveys a clear understanding of the objects and principles prefaced above, and while b-ut two embodiments have been illustrated, it should he understood that considerable changeniight be made in the construction without departing from the spirit and scope of the inven-i tated' through .the 'medium' of: the *formed tion as expressed in the appended claims. lVhat is claimed is: V 1 1.
